目前,随着载货汽车底盘的整备质量越来越大,随车起重吊机的吊重吨位也越来越大,进而对安装吊机、承载吊机重量与工作性能的副车架的强度要求也越来越高。文章设计了一种适用于大吨位随车起重吊机固定安装用的副车架,分析显示,它能够在吊机最大吊重工况下保证底盘的强度,结果证明它能够有效保障吊机工作的安全性、底盘和整车的稳定性,满足大吨位吊机安装使用的要求。
At present, as the curb weight of truck chassis is getting bigger and bigger, the hoisting tonnage of on-truck crane is also getting larger and larger, so as to install a crane, a subframe supporting the weight and working performance of the crane Intensity requirements are getting higher and higher. The article has designed a sub frame which is suitable for the fixed installation of a large tonnage truck crane. The analysis shows that it can ensure the strength of the chassis under the maximum hoisting condition of the crane. As a result, it proves that it can effectively protect the crane Work safety, chassis and vehicle stability, to meet the requirements of the installation and use of large tonnage crane.
